c2797 List initialization inside member initializer list or non static data member initializer not implemented

I m getting the following error in visual studio 2013 when i try to compile my project.

c2797:List initialization inside member initializer list or non static data member initializer not implemented.

Here is the piece of code for which it is throwing the above compiler error.

====sample.h====

enum class Process
{


  TUNNEL_IP_VERSION,  // Tunnel::IPVersion::Type
  PADDING_BYTE,
  IP_ADDRESS_FIT_ACTUAL_SIZE,
  IP_ADDRESS_FIT_IPv6_SIZE,
  PORT_NUMBER,
};

using ProcessingOrder = std::vector<Process>;

const ProcessingOrder m_ProcessingOrder =
{


  Process::TUNNEL_IP_VERSION,
  Process::PADDING_BYTE,
  Process::IP_ADDRESS_FIT_IPv6_SIZE,
  Process::PORT_NUMBER
};

Eventhough VS2013 supports c++11 feature - intialize list , why it is throughing the above error !? How to get off with this situation? What do i need to change in the code to fix this?
